Display Device Having a Plurality of Pixel Arrangement Structures

2. The display device according to claim 1, wherein, a grayscale of a data signal supplied to at least one selected from the boundary subpixel of the first boundary pixel and the boundary subpixel of the second boundary pixel is lower than a grayscale of a data signal supplied to a subpixel other than the boundary subpixel of the first boundary pixel and the boundary subpixel of the second boundary pixel when a same input image data is applied thereto.

4. The display device according to claim 3, wherein the pixel arrangement information included in the lookup table further includes information about the first arrangement structure and the second arrangement structure.

6. The display device according to claim 5, wherein the luminance ratio storage stores the luminance ratios for respective colors of the subpixels.

7. The display device according to claim 6, wherein the normal area is a selected portion of the first pixel area.

8. The display device according to claim 5, wherein each of the luminance ratios and the grayscale gain is greater than 0 and equal to or less than 1.

9. The display device according to claim 5, wherein, as the grayscale is lower, the grayscale gain decreases.

10. The display device according to claim 9, wherein the grayscale gain is 1 when the grayscale is equal to or less than a preset threshold grayscale.

11. The display device according to claim 3, wherein the pixel arrangement information included in the lookup table further includes information about a first pixel identification corresponding to an arrangement structure of the subpixels in the first pixel area and a second pixel identification corresponding to an arrangement structure of the subpixels in the second pixel area.

15. The display device according to claim 1, wherein an aperture ratio of the second pixel area is greater than an aperture ratio of the first pixel area.

17. The display device according to claim 16, wherein the data processor determines the boundary subpixel of the first boundary pixel and the boundary subpixel of the second boundary pixel based on a boundary type indicating a positional relationship between the first boundary pixel and the second boundary pixel.

21. The display device according to claim 20, wherein the data processor determines the first boundary subpixel of the first boundary pixel and the second boundary subpixel of the second boundary pixel based on a boundary type indicating a positional relationship between the first boundary pixel and the second boundary pixel.

22. The display device according to claim 20, wherein distances between the pixels of the first pixel area are smaller than distances between the pixels of the second pixel area.

23. The display device according to claim 22, wherein a shortest distance between the first boundary subpixel and the second boundary subpixel is shorter than the distances between the pixels of the second pixel area.

24. The display device according to claim 23, wherein the shortest distance between the first boundary subpixel and the second boundary subpixel is longer than the distances between the pixels of the first pixel area.

27. The display device according to claim 26, wherein sizes of the fifth, sixth, and seventh subpixels are greater than sizes of the first, second, third, and fourth subpixels.

28. The display device according to claim 26, wherein the pixels in rows adjacent to each other in the second pixel area are located diagonally to each other with respect to the first direction.
